LOCK ATTACHMENT.

' Specification of Letters Patent.

Application filed October 11, 1911.

Patented ma a, 1912. Serial No. 653,992.

whereby frail and insecure locks such as.

that upon furniture in hotels and the like and upon the doors in such rendered reasonably secure.

The invention will be fully described in the following specification and shown in the accompanying drawings, in which igure 1 is a plan View of my device, Fig. 2 an edgewise View, Fig. 3 a fragmentary central longitudinal sectional view of a series of drawers with my device applied thereto.

The reference numeral 1 designates the body of my device which is preferably stamped from a sheet of spring steel. 2 is an eye therethrough at one end thereof, and 3 an upstanding car punched from the main body 1, 4c ('lcsignates drawers of ordinary construction, 5 the partitionsbetween the drawers, 6 the key-holes, 7 the ordinary locks of the drawers, 8 the locking bolts thereof and 9 the usual recesses in the partitions 5 to receive the bolts 8, as will be understood. 'lhrough the eyes 2 are passed the chain 1.0 bothends of which are secured to the lock ll but are adapted to be disconnected therefrom by unlocking the lock 11.

From the foregoing it is believed that the construction and operation of my device will'be fully understood. The drawer 4; is locked in the usual manner. The body 1 is then thrust through the keyhole 6 until the car 3 has passed entirely through the keyplaces, may be hole, the ear 3 springing toward the body 1 during the passage ofthe latter through the keyhole, and afterward springing into 1ts normal position as shown in Fig. 8, which prevents the withdrawal of the body 1 in the same direction from which It is clear thatthe insertion of a key into thelock 7 by an unauthorized person is effectually prevented by, the body 1 and that when it is desired to open the drawer 4; the same may be readily accomplished by unlocking the lock 11, withdrawing the chain .10 from the eye 2 and forcing the body 1 into the drawer 4, when the key to the lock 7 may be used to unlock the drawer.

lVhile I have shown my device as applied toa drawer it will be understood that the same may be used with equal efficiency in a lock applied to an ordinary door or the like and to many other analogous uses; many changes in detail of construction may occur to others without departing from the spirit and scope of my invention as herein described and sworn in the accompanying drawings, and I do not therefore desire to be limited to the exact form shown and de scribed.

\Vhat I claim as new and desire to proted; by Letters Patent is- The combination in a safety device for looks of a plurality of flat members of spring material each adapted to enter the keyhole of a lock, an ear struck up from each of said members to prevent the withdrawal of said members in one direction, an eye in the opposite end of said members, a flexible member on which said flat members are strung and a lock for locking the ends 01 said flexible members together.
